To dllwiom it may concurrir Be it known that I, OSCAR H. WISENANT,

a ycitizen of the United States, residing at Chicagm'in the county of@ook and State 'ofv llinois,'have invented new and useful ImprovementsinWheel Traction Attachments, of which the following is aspeoiication.'

The invention relates to anti-slipping de-4 vices for use in connectionwith vehicle wheels rovided with pneumatic cushion or other yieldabletires, the purpose being to provideconnecting means which will admit ofrepairs being cheaply and quickly made Ainthe event of tbecomingnecessary `to re l place worn vparts. x Tlie invention relates-to theclass of de- `vicesembodyin chains arranged upon-iopposite sides oft etire and transverse chains` extendin across thetread of the tire andconnecte side cha1ns,'whereby worn chains may be quickly removed and newchains pladed ih position `with ease and despatch( The inventionconsistsof the novel features, details of construction and combination ofparts,which hereinafter will beLmore pnrticularlyset forth,- illustrated inthe accompanying drawing, and. pointedout inthe appended claim.

Referrin tothe drawing, forming a part of the application, Figure l is aside View of a portion of a. tire. provided with an anti'- slippingappliance embodying the invention. Fig. 2 is a yperspectiveview, showingmore clearly the link connection between a trans-f,

verse and a side chain. Fig`. 3 is a longitudinal section of thelinkyshowing the lock suspended thereon. Fig. 4 is aview of the partsillustrated in- 1T-1g.' 3," showin the hooked end of the linkmember'engage with the sideehain and the lock moved so as toy engageboth' the bill ofv the hook ,and the member of thelink. Fig. 5 is a viewof the parts shown in Fig. 4 .having the lock bentl about the memberofthe chain engaged by the hook member of the link. Fig-'6' is a detailperspective v iew ofv the lock folded.

upon itself.

Corresponding and like parts are referred to in the Ifollowingdescription, andv indi-` cated in all the'views of the dra-wing, by`the' same reference characters.

The traction or anti-slippin is of such construction as to removably .attheir ends to the side chains,' the purpose being to providenovel`coniect- `in'g' means between the transverse an I attachment l 4-tted to the tires of pneumatic lcu'shionland like softtread wheelsand'embodying'side chains andvtransverse chains, the latter eX-tendingacross the tread of the tire and con-' nected at their ends tothe side chains.

`. Intlie drawing the numeral l designates a side chainand 2 transversechains, which are connected tothe side chain by means of links 3. Thepresent invention relates more particularly to the'connecting link 3 andthe lock 4:, c'oper'atinor therewith.' It is to be understood that tie'transverse chainsare connected at their ends to the side chains bymeans of links 3,' so that the transverse from any cause. .The link 3is' approximately of V'- form,` one -inember terminating in a closed eye5 and the other member terminating in Ya hook 6, vwhich isadapted to becoupled togor uncoupled {roma-link ofthe 4side chain so as to admit ofthe transverse chain beingv 'quicklyplaced in position or removed.nected by theeye 5 to' one of the links of the side chain. and the hook6 is' provided to admit of the other member of the link mak-v ingdetachable'- connection with lthe side chain, "so that when required thetransverse. chain 2 may be slipped'upon the link 3 or.

removed therefrom. i When the member of The link 3is permanently con`chains maybe readily replaced when desired the link 3 having the r hook6 is disconnected i from thefside chain' the ti-ansv'ersev chain may be'either slipped uponl the link. or removed `therefrom. When thetransversechain is in position and the hook 46 engaged with 'the' .sidechain the connection is madef'secure by means ofthe lock 4,'whichf'consists'bf an oblon vlink 'of flexible vmateria1, such asw.annea ed steel or other softenedl or'pliable meta-l. The link 4f is'closedand preferably struck from sheet metal andis bendable so as to. be[doubled upon itself and again straightened without fracture.. 'Thelink{ 4e is slipped luponv the connecting-link 3 after thetransversechain hasbeen attached therel to andpriortoengaging the hook6w1th a v link of the sidegc'hain After the trans-.

verse 'Y chain Q'has been placed in posit-ion upon the link Sand .thelook 4 slipped upon the said link 3 the hook 6 is engagedjwith a `ismoved sofas to engage .the hook 6 when the said link'll is bent aboutthe linkvofthe side' chainien aged by the hook 6 andpressed toward tielink 3 sogas to engage over the 'butt or closed end of thehook 6, as4indicated `link of the side chain, after which the link4v inf-.ii

F rom the foregoing description, taken in connection With theaccompanying drawing, the advantages of the construction and of themethod Tot' operation willv be readily apparent to those skilled in theart toivliicli the invention appertains, and While I have described. theprinciple of operation of the invention, together With the device whichI noa consider to be the embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made When desired as are Within the scope of the claimappended hereto.

esmas Having thus described. the invention what is claimed as new, isatothe side chains by means of a closed eyel and having the vother memberdetachably connected' with the side chains by means of hooks, and locksfor securin'g the hook memy bers of the V-1inks to the side chains, saidlocks consisting of oblong links having one end engaging the hooks,thence bent about the membersv of the side chains engaged b3' the hooksand engaged with the butts or closed ends of the hooks, substantially inthe manner specified.

In testimony whereof I atlix my signature in presence of two witnesses.i
